時代不同，⾯面對資料的態度也不同...

● 存得起來的，叫做Storage (儲存)!

● 看得到的，叫做Data (資料)!

● 看得懂的，叫做Information (資訊)!

● ⽤用得出來的，才能夠叫做Intelligent (智慧)

google-api-utility模組開發歷程

透過初始化設定之後， 即可以直接進⾏行api呼叫動作 !1. 設定檔抽離 2. 結合request模組進⾏行API呼叫 3. Access Token cache

google-api-utility module基本資訊 ● https://github.com/peihsinsu/google-api-utility 安裝 ● npm install google-api-utility 操作 ● apiutil.init(config) ● apiutil.request(options, callback)

var auth = require('google-api-utility')

auth.init({

scope: 'https://www.googleapis.com/auth/bigquery https://

www.googleapis.com/auth/cloud-platform',

client_secret: '/path-to-client_secret.json',

key_pem: '/path-to-key.pem'

});

使⽤用範例 - 初始化

此處需要綁定所欲呼叫的API相關授權之Scope位置

設定client_secret.json與相關pem檔案位置，供jwt運算使⽤用

使⽤用範例 - 呼叫BigQueryvar request = auth.request;

var bqurl = 'https://www.googleapis.com/bigquery/v2/projects/%s/datasets';request({ url: util.format(bqurl, project), method: 'GET' }, function(err, req, doc){ // implements });

同原request模組操作⽅方式

結合原request模組之function，供api呼叫使⽤用

Google API Explore HTTPS://developers.google.com/apis-explorer/

Google API Explore - Query

Google API Explore - Auth

Operation Scope

Google API Explore - Response

Idea...● bigquery.init({...configurations...})

● bigquery.[what].[do](...)

- bigquery.dataset.list(....)

- bigquery.table.load(..., callback)

bigquery module基本資訊 ● https://github.com/peihsinsu/bigquery 安裝 ● npm install bigquery 操作 ● bigquery.init(config) ● bigquery.[category].[operation](options, callback)

重新包裝 - bigquery模組var bq = require('bigquery') , prjId = 'your-bigquery-project-id';

bq.init({ client_secret: '/path/to/client_secret.json', key_pem: '/path-to-key.pem'});

bq.dataset.list(prjId, function(e,r,d){ if(e) console.log(e); console.log(JSON.stringify(d)); });

bigquery模組可參考：https://github.com/peihsinsu/bigquery

透過bq呼叫某個操作之下的function

Source Code...var util = require('util') , auth = require('google-api-utility') , request = auth.request , _ = require('underscore') exports.init = auth.init; exports.job = { token: '', listds : function(project, cb){ var bqurl = 'https://www.googleapis.com/bigquery/v2/projects/%s/datasets'; request({ url: util.format(bqurl, project), method: 'GET' }, cb?cb:auth.commonCb); }, … (skip) }

封裝相同類別的api在⼀一起!ex: job相關的放在job物件中

應⽤用.... sql2bq

sql2bq module基本資訊 ● https://github.com/micloud/sql2bq 安裝 ● npm install sql2bq -g 操作 ● sql2bq-init ● sql2bq-load -q [SQL] -t [table]

Google’s Node.js SDK

Operation with googleapisvar googleapis = require('googleapis'); !var jwt = new googleapis.auth.JWT( '429100748......hv3@developer.gserviceaccount.com', '/path/to/key.pem', null, [

'https://www.googleapis.com/auth/bigquery', 'https://www.googleapis.com/auth/cloud-platform'

]);

Operation with googleapisjwt.authorize(function(err, tokens) { googleapis.discover('bigquery', 'v2').execute(function(e,client) { if(e) console.log(e); else client.bigquery.datasets.list(param).withAuthClient(jwt)

.execute( function(err, response) {

if(err) console.log(err); console.log(JSON.stringify(response)); }); }); });

應⽤用... gapis

gapis module基本資訊 ● https://github.com/peihsinsu/gapis 安裝 ● npm install gapis -g 操作 ● gcli -d project=[PROJECT_ID] -f [API FUNCTION]
